Seville options

I am considering buying a 2003 or 2004 Seville. I use Compnine to check options for a vin number, but this does not help to identify options that are available model wide. One thing that I do not have is a list of available options for those years. Edmunds does not show options any longer, just standard features. From this I can tell that SLS and STS have a few different standard features. 2004 does not have a STS but wondered how many of 2003 STS features were carried over as SLS in 2004? Anyone know of a web site that still has info on 2003/2004 Seville models and options?

Seville STS was discontinued in '03, Seville SLS is the lesser model and was discontinued in '04.
By '03 pretty much all the options in the STS were available in SLS except:
Magnaride suspension (SLS has CVRSS)
Northstar V8 4.6l LD8 high-torque 275 hp, 300 lb·ft
Perforated seats
Less wood trim
I believe the '03 and up SLS had the fog lights as standard (at least were available as an option part of the STS appearance package).

Re: Seville options

All Seville possible RPO's are listed in the GM service manual as well as in Alldata. You can then bounce the master list against the list on your sticker under the spare tire cover to find what's in THAT car.

As posted in another thread: American STS stopped production in 06/03. SLS continued into 12/03 (4 months into the 2004 "model year") so there are legitimate "2004" SLS out there. A "2004 STS" would be a Canadian model only and first registered in a country that uses registration date as "model year". From early 2003, total Seville sales dropped like a rock.

(One of our members, in England, has a "2001 STS". ............... but it was built in early 1999 and has the flat tappet engine, not the roller cam engine of 2000 [after 08/99] and later........................)
